Divisor is two, three-digit division, from the content of knowledge mainly includes the division of law and trial business method, from the choreography point of view, according to the divisor is a division, two, three, divided into three cycles Circle, take decentralized difficulties, step by step, the way to improve step by step. Due to its multi-content and strong comprehensiveness, it has always been the focus and difficulty of mathematics teaching. In the divisor is the one-digit division, the teaching material on the divisible, there is a remainder, the middle of the business, there are zero at the end of a variety of circumstances, in accordance with the degree of difficulty, respectively, made arrangements so that
